To all whom it may concern": Be it known that I, HERMAN @KRUSE, a

citizen of the United States, residing at J er- My invention relates to improvements in inks, and more rtieularly to stencil ink,

ographing. i v

In my improved ink, I preferto employ a color base such as carbon, barium sulphate, or alumina hydrate, together with glycer- 1 ine, and a saponified-varnish for a consistum carbonate), twenty-four pounds of gum rosin, six pounds of'kerosene oil, and

pounds of parafin oil (No;' 903 Swan & Finch), These ingredients for the consistency element or varnish may be heated in a steam jacketed kettle" until all the water is evaporated.

A good quality of ink of the character described may be provided by gmixing p 8 parts by. weight of carbon 7 2 parts by. weight of malorie blue 20 parts by weight of glycerine duplicating and mime- A licationfileztneceinber is, 19211; No. 522,888.

If it is desired to use barium sulphate, in-

stead of 8 parts byweight'of carbon and 2 parts malorie'blue, partsby weight of barium sulphate may be substituted, or '20 parts by weight of alumina hydrate.

.Without saponification, the ink may be made with the color base and glycerine-by addingrosin and oil substantially as fol lows . 8 parts by weight of carbon Y 2 partsby weight malorie blue 20 parts by weight glycerine 24 parts by weight rosin 56 parts bv weight mineral oil such as kerosene 6 parts to. parts ofparafi'm. Of course it will beunderstood that varivous modifications may be made in therproportions and mixing of theingredientswithout departing from the spirit of the invention as claimed. I
